Description

Technical Field

[0001] This utility model belongs to the field of bathroom technology, and in particular relates to a press-to-install quick-release filter cartridge device and bathroom equipment. Background Technology

[0002] With water pollution becoming increasingly serious, the demand for bathroom products with filtration functions (such as smart toilets and water purifier faucets) has surged. However, the mainstream products on the market currently face two major technological bottlenecks.

[0003] 1) Insufficient filtration efficiency: Most bathroom filters use only a single filter element (such as PP cotton), which cannot cope with water quality with high impurities (rust, sediment) and chemical pollution (residual chlorine, COD), resulting in limited filtration effect, especially with a high failure rate in areas with poor water quality.

[0004] 2) Poor maintenance experience: Traditional filter replacement requires special tools to disassemble the threaded or clamp structure, which is complicated to operate and requires a lot of force to disassemble, affecting the user experience.

[0005] To improve filtration performance, some solutions introduce composite filter technology, but most of these are used in water purifiers or filters in other industries.

[0006] For example, the filter with a composite filter element, authorized by announcement number CN204958553U, adopts a multi-layer filter material integrated design, which can intercept particulate impurities and adsorb residual chlorine, achieving dual filtration. It has a good filtration effect when used under poor water quality conditions, but disassembly and assembly still require rotating the outer shell multiple times, which cannot achieve "quick disassembly and quick replacement".

[0007] Another example is a filter element replacement structure with publication number CN104645681A, which achieves composite filtration through a split filter element diaphragm. However, during installation, multiple sealing interfaces need to be aligned and the buckles need to be manually tightened, which is cumbersome and poses a risk of leakage.

[0008] Based on this, the present invention provides a novel press-to-install quick-release filter cartridge device and bathroom equipment to overcome the above-mentioned defects. Utility Model Content

Detailed Implementation

[0063] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0064] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The present invention will be described in detail with reference to specific embodiments:

[0065] like Figures 1 to 10 As shown, this utility model provides a press-and-release filter cartridge device, which includes:

The left filter element chamber 22 and the right filter element chamber 23 are connected through the filter column 50.

[0071] The buckle assembly 4 has an open state and a locked state;

[0072] When the latching assembly 4 extends out of the limiting chamber 21, the latching assembly 4 is in an open state;

[0073] When the buckle assembly 4 moves into the limiting chamber 21, the limiting chamber 21 limits and constrains the buckle assembly 4, and the buckle assembly 4 is in a locked state and clamps the buckle post 11, thereby realizing the detachable locking between the filter element housing 1 and the filter element body 2.

[0074] The installation process of the press-and-release filter element device in this utility model:

[0075] In the initial state, the latching assembly 4 extends out of the limiting chamber 21 and is in the open state;

[0076] When the user presses the filter element end cap 5, the buckle assembly 4 first contacts the buckle post 11, and at this time the buckle assembly 4 and the buckle post 11 remain relatively stationary.

[0077] Continue pressing the filter element end cap 5. Driven by the pressing transmission assembly 3, the filter element body 2 moves axially towards the latching post 11, pushing the latching assembly 4 into the limiting chamber 21.

[0078] The inner wall of the limiting chamber 21 is switched to the locking state by the forced snap-fit ​​assembly 4, and the snap-fit ​​post 11 is clamped, thus completing the single-action locking of the filter element housing 1 and the filter element body 2.

[0079] Disassembly process of the press-to-release filter cartridge device:

[0080] Press the filter element end cap 5 again, and the press transmission assembly 3 will return to its initial state. The buckle assembly 4 will move axially out of the limiting chamber 21 as the press transmission assembly 3 is activated, releasing the inner wall constraint. The buckle assembly 4 will then switch to the open state, releasing the buckle post 11, thus completing the quick disassembly of the filter element body 2 and the filter element housing 1.

[0081] The quick-release filter cartridge device of this utility model mainly consists of a filter cartridge housing 1, a filter cartridge body 2, a pressing transmission assembly 3, a buckle assembly 4, and a filter cartridge end cap 5. With the cooperation of the above units, the quick installation and disassembly between the filter cartridge housing 1 and the filter cartridge body 2 can be realized, which is convenient for quick replacement of the filter cartridge.

[0082] Meanwhile, when the filter cartridge device is in use, water enters through one of the matching columns 12, passes through the left filter cartridge chamber 22, the filter column 50, and the right filter cartridge chamber 23 / right filter cartridge chamber 23, the filter column 50, and the left filter cartridge chamber 22 in sequence, and then flows out through the other matching column 12. The corresponding filter cartridge structure can be placed in the filter cartridge chamber to achieve multiple filtration effects.

[0083] Furthermore, a through hole 51 is provided at the position opposite to the left filter chamber 22 and the right filter chamber 23 of the filter element end cap 5, and a positioning groove 52 is provided on the inner wall of the through hole 51;

[0084] A container end cap 6 is installed within the through hole 51. The outer wall of the container end cap 6 is provided with a locking platform 60. The locking platform 60 cooperates with the positioning groove 52 to achieve a detachable connection between the container end cap 6 and the filter element end cap 5. It should be noted that the specific structure of the positioning groove 52 and the locking platform 60 is not limited in this invention; those skilled in the art can design them themselves, as long as a detachable connection between the container end cap 6 and the filter element end cap 5 can be achieved.

[0085] During use, the container end cap 6 can be removed, and the filter element body can be placed into the left filter element chamber 22 and the right filter element chamber 23 through the through hole 51 for easy replacement of the filter element body. At the same time, filter elements of different materials can be encapsulated in the left filter element chamber 22 and the right filter element chamber 23 to ensure the filtration function and service life of the filter element body.

[0086] In addition, the sequential filtration of the right filter chamber 23, the filter column 50, and the left filter chamber 22 can effectively extend the service life of filter elements of different materials and achieve consistency in the service life of the filter element body and the filter element device.

[0087] Furthermore, the filter element end cap 5 is provided with two first connecting posts 53 on the side near the filter element body 2, and the first connecting post 53 is provided with an axially penetrating first central through hole;

[0088] The filter element body 2 is provided with two second connecting posts 25. The second connecting post 25 is provided with an axially through second central through hole. When the filter element end cap 5 is assembled with the filter element body 2, the second central through hole and the first central through hole are coaxially connected to form an assembly channel.

[0089] A first limiting protrusion 54 is provided on the inner wall of one of the second central through hole and the first central through hole, and an internal thread is provided on the inner wall of the other. A first locking member 55 is provided in the assembly channel. The head of the first locking member 55 abuts against the first limiting protrusion 54, and the tail of the first locking member 55 is inserted into the assembly channel and screwed into the internal thread, thereby realizing the fixed connection between the filter element end cap 5 and the filter element body 2. The connection method is simple and reliable.

[0090] Furthermore, the mating groove 24 is provided with a filter nozzle 56 near the filter element end cap 5 for initial filtration. It should be noted that the filter nozzle 56 is not limited in position in this invention; existing technologies can be used, and all are within the protection scope of this invention.

[0091] When water flows into one of the mating columns 12 of the filter cartridge housing, it passes through a filter nozzle 56 and flows into one of the filter cartridge chambers. Under the action of the filter cartridge in this chamber, various particulate impurities in the water can be effectively removed, and large particles such as rust, silt, and insect eggs can be blocked. Then, it flows into another filter cartridge chamber through the filter column 50 of the filter cartridge end cap 5. Under the action of the filter cartridge in this chamber, the required filter media is slowly released, so that residual chlorine in the water can be removed or scale can be inhibited in the filter cartridge chamber. After that, the water flows through another filter nozzle 56 and out of another mating column 12. The water quality can ensure the stable operation of the pipeline and valve core, reduce the occurrence of failures, and extend the service life of the product.

[0092] Furthermore, the press-to-install quick-release filter cartridge device also includes:

[0093] Press cover 7, the press cover 7 is provided with two pillars 70 on the side near the filter element end cover 5, the outer peripheral wall of the pillars 70 is provided with a first sealing groove 71, and a first sealing ring is embedded in the first sealing groove 71.

[0094] The column 70 is coaxially inserted into the first central through hole of the filter element end cover 5, compressing the first sealing ring to deform and form a dynamic seal with the inner wall of the first central through hole, thereby enhancing the connection sealing performance. Furthermore, the press cover 7 is mounted on the outer end face of the filter element end cover 5 on the side away from the snap-fit ​​assembly 4, achieving a sealed connection between the press cover 7 and the filter element end cover 5, further enhancing the connection sealing performance.

[0095] Furthermore, the outer peripheral wall of the mating post 12 is provided with a second sealing groove 121, and a second sealing ring is embedded in the second sealing groove 121; the mating post 12 is coaxially arranged in the mating groove 24 of the filter element body 2, and the deformation of the second sealing ring by compression forms a dynamic seal with the inner wall of the mating groove 24, thereby enhancing the connection sealing performance. It should be noted that there are various ways to achieve the external connection of the mating post 12, such as threaded connection, snap-fit ​​connection, etc. This embodiment only shows the threaded connection form.

[0096] Furthermore, the pressing transmission assembly 3 includes a transmission component 30, a spring component 31, a rotating component 32, a pressing component 33, and a sealing head 34.

[0097] The end of the transmission component 30 passes through the center hole of the spring component 31, the center hole of the rotating component 32, and the center hole of the pressing component 33 in sequence and extends into the limiting chamber 21, where it is threadedly connected to the buckle assembly 4.

[0098] The sealing head 34 is disposed at the end of the movable chamber 20 away from the limiting chamber 21, thereby sealing one end of the movable chamber 20; one end of the spring member 31 abuts against the sealing head 34, and the other end abuts against the axial end face of the rotating member 32; it should be noted that the sealing head 34 can be a locking nut, as long as it can achieve sealing at one end, and no specific limitation is made in this utility model.

[0099] One of the rotating component 32 and the pressing component 33 is provided with a guide post 35, and the other is provided with a guide hole 36. They are connected as one unit through the cooperation of the guide post 35 and the guide hole 36. The guide post 35 and the guide hole 36 refer to the plug-in structure used to connect the rotating component 32 and the pressing rod 33. Specifically, it can be achieved by the cooperation of a cylindrical protrusion and a corresponding groove. This structure ensures the axial synchronous movement of the two components while allowing relative rotational freedom.

[0100] The rotating member 32 has a first inclined surface 321 and a second inclined surface 322 that are inclined in the same direction on the end face facing the pressing member 33. The radial depth of the first inclined surface 321 is less than the radial depth of the second inclined surface 322. The first inclined surface 321 and the second inclined surface 322 refer to the stepped inclined surfaces formed on the end face of the rotating member 32. The rotation angle of the rotating member 32 is controlled by the angle of the inclined surfaces.

[0101] The end face of the pressing member 33 facing the rotating member 32 is provided with a serrated third inclined surface 331 corresponding to the first inclined surface 321 and the second inclined surface 322.

[0102] The inner wall of the movable chamber 20 near the limiting chamber 21 is provided with a limiting inclined surface 201 that cooperates with the first inclined surface 321 and a guide inclined surface 202 that cooperates with the second inclined surface 322. The limiting inclined surface 201 and the guide inclined surface 202 refer to the structures provided on the inner wall of the movable chamber 20 that match the first inclined surface 321 and the second inclined surface 322 of the rotating member 32, and are used to constrain the position of the rotating member 32.

[0103] The inner wall of the active chamber 20 is also provided with a guide groove 203 extending along the length direction. The outer peripheral walls of the rotating member 32 and the pressing member 33 are provided with guide platforms 332 that slide in cooperation with the guide groove 203. The cooperation between the guide platform 332 and the guide groove 203 is used to limit the linear motion trajectory during the pressing operation.

[0104] It should be noted that the transmission principle of the press transmission component 3 can be referred to the press principle of a ballpoint pen, which will not be elaborated here.

[0105] Specifically, the buckle assembly 4 includes a buckle base 40, a first buckle 41, a second buckle 42, and a torsion spring 43.

[0106] The first buckle 41 and the second buckle 42 are rotatably connected to the buckle base 40 via a rotating shaft 44. A torsion spring 43 is sleeved on the rotating shaft, with one end of the torsion spring 43 connected to the first buckle 41 and the other end connected to the second buckle 42. It should be noted that this invention also includes a limiting structure on the first buckle 41 and / or the second buckle 42 to limit the opening angle of the buckle assembly 4. The design of the limiting structure is a conventional design in this field and will not be described in detail here.

[0107] Installation process of the press-to-remove filter cartridge device:

[0108] Assembly of buckle assembly 4: First, torsion spring 43 is sleeved on rotating shaft 44, and one end of torsion spring 43 is connected to first buckle 41 and the other end is connected to second buckle 42. Then, first buckle 41 and second buckle 42 are fastened and installed on buckle base 40 to realize the assembly of buckle assembly 4.

[0109] Assembly of the pressing transmission assembly 3 and the filter element body 2: The transmission component 30 passes sequentially through the center holes of the spring component 31, the rotating component 32, and the pressing component 33, then through the movable chamber 20 of the filter element body 2 and into the limiting chamber 21, and is finally threadedly fixed to the snap-fit ​​assembly 4. Next, the sealing head 34 is sealed to one end of the movable chamber 20, thus limiting the pressing transmission assembly 3 to the movable chamber 20 of the filter element body 2.

[0110] Assembly of the filter element body 2 and the filter element end cap 5: Align the second central through holes of the two second connecting posts 25 of the filter element body 2 with the first central through holes of the first connecting post 53 on the same axis, and insert the first locking member 55 into the assembly channel to achieve a fixed connection between the filter element end cap 5 and the filter element body 2. Next, align the locking platform 60 of the container end cap 6 with the positioning groove 52 of the filter element end cap 5, and rotate the container end cap 6 to fix the container end cap 6 onto the filter element end cap 5.

[0111] Assembly of the press cover 7 and the filter element end cover 5: The column 70 of the press cover 70 is coaxially inserted into the first central through hole of the filter element end cover 5, and the press cover 7 is mounted on the outer end face of the filter element end cover 5 away from the buckle assembly 4, so as to achieve a sealed connection between the press cover 7 and the filter element end cover 5.

[0112] Assembly of filter element body 2 and filter element housing 1:

[0113] In the initial state, the latching assembly 4 extends out of the limiting chamber 21, and under the action of the torsion spring 43, the first latch 41 and the second latch 42 separate in opposite directions, so that the latching assembly 4 is in the open state. When the mating groove 24 of the filter element body 2 is aligned with the mating post 12 of the filter element housing 1, and then the user presses the pressing cover 7, the latching assembly 4 first contacts the locking post 11, at which time the latching assembly 4 and the locking post 11 remain relatively stationary.

[0114] Continue pressing the pressing cover 7. The latching assembly 4 drives the pressing member 33 to move away from the latching assembly 4. At the same time, the third inclined surface 331 of the pressing member 33 interacts with the inclined surface of the rotating member 32, causing the rotating member 32 to change position through sliding and rotation on the inclined surface, and compressing the spring member 31, causing the guide platform 332 of the rotating member 32 to disengage from the guide groove 203 of the filter element body 2. Since the guide groove 203 has the function of restricting the movement trajectory, but the guide platform 332 of the pressing member 33 does not disengage from the guide groove 203 of the filter element body 2 and is confined within the guide groove 203, it pushes the rotating member 32 and the transmission member 30 to move away from the latching assembly 4, thereby pushing the latching assembly 4 into the limiting chamber 21. The inner wall of the limiting chamber 21 is forced to switch the latching assembly 4 to the locked state, that is, the torsion spring 43 stores energy, and the first latch 41 and the second latch 42 tighten towards each other and clamp the locking post 11, completing the single-action locking of the filter element housing 1 and the filter element body 2. At this time, a "click" sound is heard, indicating that the latching assembly 4 and the locking post 11 have completed the locking connection. Due to the influence of the limiting inclined surface 201 and the guide inclined surface 202 of the filter element body 2, the rotating part 32 can be accurately locked at the limiting inclined surface 201 of the filter element body after rotation, realizing mechanical self-locking.

[0115] Disassembly process:

[0116] Press the pressing cover 7 again to drive the pressing member 33 to move. At the same time, the third inclined surface 331 of the pressing member 33 interacts with the inclined surface of the rotating member 32, causing the rotating member 32 to change position by rotation. At this time, the compressed spring member 31 releases energy and provides a rebound force, causing the guide platform 332 of the rotating member 32 to slide into the guide groove 203 of the adjacent filter element body 2, completing the state switch and causing the rotating member 32 and the pressing member 33 to slide back to their original positions. During this process, the transmission rod 30 drives the buckle assembly 4 to slowly move out of the limiting chamber 21 of the filter element body 2. Under the action of the torsion spring 43, the first buckle 41 and the second buckle 42 separate in opposite directions, loosening the clamping of the buckle post 11.
